Title: Improved method and apparatus for separating air and gases from liquids
IPC: B01D19/00
Filed: 1922-05-29
Abstract: 203,034. Elliott, W. S. May 29, 1922. Liquids and gases, separating.-Gases are extracted from liquids by passing the liquid through a heater, in which a definite pressure is maintained, and supplying sufficient heat to raise the liquid to boiling and to effect the evaporation of a substantially constant percentage of the liquid, means being preferably provided for recovering the heat from the gases and vapours liberated. The liquid entering by the supply pipe 6 passes through a condenser 4, where it is preheated, and thence by a pipe 12 and valve 13, operated by a float 14 in the evaporating chamber 3, to a heater 2, where it flows through a series of tubes 17-21 and is heated such as bv steam admitted through an inlet 22. Preferably the last group of tubes 21 has a greater cross-sectional area than any of the other groups, so as to permit evaporation. A temperature gauge 23 may be fitted to the heater. The liquid flows from the heater to the evaporating chamber 3 over spray pans 24 and may be tapped off by a vented outlet pipe 25, the vapours passing by a passage 27 to the condenser 4. By means of an ejector 5 the whole apparatus may be maintained at any desired pressure up to atmospheric. Specincation 187,700 is referred to.

Abstract: 221,558. Senior, J. H. June 12, 1923. Puzzles.-In amusement devices, of the kind in which a number of relatively-movable members each carry parts of a design which is deciphered by a relative movement of the members, each member carries the complete design partly disguised by the addition of extraneous matter so that some indication is given of the ultimate design to be produced when the members are placed in correct relative position. Fig. 3 shows two circular members a, c in correct position, the extraneous parts of the design on one disc being shown in full lines and of the other in broken lines. The centres of the members may be provided with a design f so that changing effects are produced by rotation of the discs. One of the members may carry two designs in monogrammic formation, as shown in Fig. 4, and operates in connection with two separate disguised designs on a second member so that relative movement of the members produces a dissolving effect from one design to the other. The designs may be formed on concentric cylindrical members or on members which have a relative sliding movement. The front plate may be formed of ground or clear glass with all parts except the design rendered opaque, or the design may be cut out from the material of the plates. Operating mechanism may be employed to provide a pause when the members are in correct relative position for the design to be deciphered. Suitable lighting may be employed, and a coloured member may be provided at the rear of the device.

Abstract: 402,753. Cleaning metals. JONES, H. D., Market House, Aberavon, Port Talbot, and TAYLOR, F. G., Dulais Fach, Tonna, Neath, both in Glamorgan. May 31, 1932, No. 15406. [Class 82 (ii).] Tinplates are passed through a branning machine on one or more endless conveyers, and are held on the conveyer or conveyers by one or more electro-magnetic devices acting through each conveyer. Two conveyers arranged in series are preferably employed, means for turning the plates being provided between the conveyers. The machine comprises two units A B each provided with an endless belt conveyer 1 of magnetic or non-magnetic flexible material passing round driven rollers 2 3 and adjustable idler rollers 4 5. The bran is retained on the belts by levelling rolls or by troughs formed in the conveyer belts by rollers 6 7 and 6a 7a on the upper and lower sides of the belts respectively. Between the troughs and close to the under side of each belt is an electro magnetic table or platen 9 which holds the plates s on the belt. The plates are discharged from unit A by a gripping roller 10 co-operating with the roller 3, or the rollers 3 10 may be magnetic. The roller 10 can be moved round the roller 3 and is adjusted to deliver the plates into guides 13 so that the plate is turned before passing on to the conveyer of the unit B. The plates are delivered from the unit B into guides 13 and are then passed by a guide roller 14 to cleaning rolls 15. Surplus material is caught by a plate 16 and removed at 17. Cleaning rolls may be associated with any or all of the conveying units. According to the Provisional Specification the conveyers may be inclined and arranged one above the other, the plates passing from the upper conveyer downwardly through guides which invert them before delivering them to the lower conveyer. Alternatively the conveyers may be in substantially the same horizontal plane, the plates being passed without reversal from the upper side of the first conveyer to the under side of the second.

Title: Altimeters, aneroid barometers and pressure measuring instruments
IPC: G01L7/00
Filed: 1935-05-29
Abstract: 457,473. Electric signalling systems. McLELLAN, A., 30A, Peters Court, Porchester Road, Bayswater, London, and WRIGHT, G. M., Broom Hall, Bicknacre, Chelmsford. May 29,1935, No. 15582. [Class 40 (i)] [See also Group XIX] Comprises an aneroid type of altimeter or other pressure measuring instrument in which the spring 6 opposing the movements of the box or capsule 1 is constituted by a rotating bar subjected to bending strain. Fast with the moving face of the box 1 is an abutment member 3 free to move between two closely spaced adjustable limit stops 4, 5. A bar 6 of circular section runs in a knife edge bearing 7 the housing of which is fixed to the box 1, and a second knife-edge bearing 8 carried by the base 2 and acting as a fulcrum about which the bar may bend. At the end of the bar 6 is another knife edge bearing 9 the housing of which is attached by a chain 10 to a shaft 11. The bar 6 is rotated from a motor 14 through shafts 13 and gearing 12, while a shaft 15 driven from the same motor carries a friction wheel 16 which can be moved across the surface of a friction wheel 18 on the shaft 11. The wheel 16 is shifted longitudinally on its shaft by solenoids 19, 20 in circuit with the stops 4, 5 so that when the member 3 engages one or other of these stops the wheel 16 is shifted to one side or other of the centre of the friction wheel 18 to drive the shaft 11 in one direction or other and influence the bending of the shaft 6 and move the member 3 away from its stop. An automatic brake, not shown, holds disc 18 in whatever position it may be at such instant when the wheel 16 crosses the centre of the disc 8. The force applied through the spring thus always balances the force exerted on the box by the atmosphere. Readings of height or pressure are obtained by a counter or the like 21 driven from the shaft 11.
